I have the following Model which is working fine (1st image).
I'm running a Network Analyst Location-Allocation. I want to iterate both Facilities and Demand Locations. So I'm calling a sub model (2nd image) to iterate the demand locations, which is stored as differents shapefiles within one folder.
However, when the model finishes it only used one shapefile from that folder and not all 4 shapefiles that it contains.
Can you figure out what I'm missing?
